PAPER-GUIDE FOR TYPE-WRITERS.

SPECIFICATION forming part Of Letters Patent No. 691,503, dated January 21, 1 902.

Application filed April 2, 1901. Serial No. 54,059., (No model.)

To aZZ whom, it may concern:

Be it known that LALBERT SWINDLEHURST, of the city of Montreal, in the county of Hochelaga, in the Province of Quebec, Canada, have invented certain new and useful Improvements in Paper-Guides for Type-VVriters, of which the following is a specification.

My invention relates to improvements in paper-guides for type-writers, and particularly to that class in which two sets of U-' shaped bars of graduated heights are supported in two frames above the platen or impression-roller, and each pair of which when operated from the keys is designed to be given a downward swing to a central point between the two sets and directly onto the paper on the platen or roller to give the impression; and the object of the invention is to devise a paper-guide which will not interfere with the free passage of the paper no matter what the width of such may be, which will not be liable to be struck by the type, and thus deleteriously afiect such type, and which it will not be necessary to adjust; and it consists, essentially, of the two plates attached to or forming part of the bottom of the type-bar frames and extending laterally inwardly with a curved upwardly-extending lip, such plates extending forwardly under the frame and over the scale-bar, the parts being otherwise constructed and arranged in detail as hereinafter more particularly explained.

Figure 1 is a perspective view of portion of a type-writer, showing the parts to which my invention relates. Fig. 2 is a cross-section. Fig. 3 is a detail of one of the plates.

In the drawings like letters of reference indicate corresponding parts in each figure.

A is the platen of the type-writer, which is supported in suitable bearings in the end of the carriage B and is provided with the usual turning-knobs a.

C O are the type-bar frames, which are supported on the standards D, forming a portion of the main frame.

0 represents the innermostty'pe-bars, the remaining type-bars on the outside increasing in'length from inside to outside. The bars are substantially reverse-U-shaped in form, the type being at the top thereof, and thcirposit-ion is shown mainly by dotted lines.

E E are plates, being somewhat in the form of a compound curve in cross-section and formed up with attaching-lugs e e, by which they are fastened to the bottom of the frame C C by the screws 6. The inner ends of each plate E are formed with an upturned curved lip 9 preferably straight in 'crosssection, such lip being on a line with the impressionpoint on the platen.

It is not. necessary here to describe the ribbon nor the way it is fed; but it is sufficient to state that the ribbon is brought in between the lips e at the proper time that the impression is delivered on the paper on the platen from the type on the type-bar midway between the ends of the lip e The scale-bar F, it will be noticed on reference to Figs. 1 and 2, is supported on suitable arms f, attached to or forming part of the frame. The scale-bar F extends into proximity with the platen, as indicated. The course of the paper is shown by dotted lines in Fig. 2, such paper passing over the platen and the apron A.

Heretofore the fingers that served as a guide for the paper to carry it past the impressionpoint on the platen were supported on a bar extending from end to end of the carriage above the apron A, the fingers being substantially on a triangular frame, with the points of the fingers extending underneath the type-bar frames onto the scale-bar. Such fingers were longitudinally adjustable on their supporting-bar for different widths of paper, and consequently if the operator of the machine forgot to adjust them properly they might when the carriage was laterally adjusted during the operation come underneath the point where the type strike on the platen,and thereby inj uriouslyafiect the type. It was also necessary to adjust them for different widths of paper and for envelops. The laterally-extending portion of the fingers being below the level of the top of the platen also formed an obstruction with which the paper was liable to come in contact, and thereby prevent the paper feeding properly. All these objections are entirely obviated by my construction of plate and lips, which being upturned at the inner ends allow the paper to pass freely underneath in both directions and yet effectually guide the paper over the platen. The lips being also supported by the type-bar frame will form no obstruction to the impression of the type, as was the case in the 01d form, where the type might come in contact with the fingers, and thereby prevent any impression being made upon the paper.

What I claim as my invention is 1'. In a paper-guide for type-writers, the combination with the platen and the type-bar frames located above the same separated centrally, of a plate intermediate of the platenand type-bar frames and attached to or forming part of the bottom of each frame and provided with an inwardly-extending lip as and for the purpose specified.

2 In a paper-guide for typewriters,v the combination with platen and the type-bar frames separated centrally, of a plate attaclied'to or forming part of the bottom of each frame and provided with an inwardlyextending lip and curved in cross-section, so

, as to hold the paper down as and for the purpose specified. v

3. In a paper-guide for type-writers, the combination with the platen and the type-bar frames separated centrally, of a plate curved in cross-section and provided with an inwardly-extending upturned lip and having suitable lugs whereby it is fastened to the bottom of each type-bar frame as and for the purpose specified.

4. In a paperguide for type-writers, the

combination with the platen suitably journaled in the carriage, of the type-bar frames above the platen having inwardly-extending portions between the type-bar frames and platen designed to extend over the paper and hold it down as itpasses laterally underneath the same as and for the purpose specified.
